We used a device with high spatial resolution to measure changes in plantar pressure distribution under the metatarsal head while leaning forwards within a positional range where digital pressure did not rapidly increase. Twenty-six healthy individuals moved forwards while standing at uniform velocity by tracking a target spot displayed on a visual monitor in front of them. The center of pressure in the foot in the anteroposterior direction (CoPy) and the plantar pressure distribution were recorded during the tracking task. Positions of the foot and pressure are represented as either relative distance from the heel to the total length of the foot (%FL) or from the medial surface to the width of the foot (%FW). The force exerted on the metatarsal head increased according to the amount of forward lean, and began to decrease at around 65%FL. The mean position of maximal pressure under the metatarsal head in the quiet standing position (QSP) was located slightly posterior to or between the second or third metatarsal head. This position moved 8.3%FW inwards and 1.3%FL forwards when CoPy was moved from QSP to 60%FL position. The metatarsal head was separated into parts of 1st, 2nd-3rd, and 4th-5th. Among them, the increase in maximal force from QSP was the greatest in parts of 2nd-3rd, whereas the rate of change in pressure in each part was the greatest in parts of 1st. These properties of plantar pressure might provide important positional information for postural control while standing.
